CHARLES HARRISON, OF DAVENPORT, \VASHINGTON.

FEEDER FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 462,434, dated November3, 1891.

Application filed March 28, 1891- Serial No. 386,770. (N0 model.)

To all whom, it may concern.-

Be it known that 1, CHARLES HARRISON, a citizen of the United States,residing at Davenport,in the county of Lincoln and State of \Vashington,have invented a new and useful .Feeder for 'lhrashing-Machines, of whichthe following is a specification.

This invention relates to thrashingmachines, and is more particularlyafeeding device attached thereto and serviceable for feeding the grain tobe thrashed to the cylinder of the thrashing-machine.

The invention consists of the specific construction of parts hereinaftermore fully described and claimed, and as illustrated on the two sheetsof drawings, wherein- Figure 1 is a general perspective View of thisdevice in operative position. longitudinal section of the same. Fig. 3is a front elevation, with the boards removed and the feeder folded.

Referring to the said drawings, the letter Y designates the cylinder ofthe thrashing-machine, below which is the usual concave O, and F is thefeed-board for directing the grain between these parts in the usualmanner.

WV is the wooden framework supporting these m embers, and His the hoodabove them. Within this hood is pivoted the swinging fender S, and inbrackets K, near the top of the entrance to said hood, is journaled thetriangular beater B, whose shaft is connected by a belt bwith a pulleyon the main shaft M, which is journaled in the wooden frame V and isdriven by power applied to the main wheel m, as will be understood.

The letters X designate extensions of the frame-work XV, each of whichextensions is in two pieces connected by hinges hon their upper sides,the inner piece being bolted or otherwise secured to the frame-work Wand the outer piece being supported by its knucklejointwith theinnerpiece in amannerbest seen in Fig. 1. This peculiar construction offeederframe permits it to be folded, as seen in Fig. 3, when theguide-boards have been removed. Said boards G G are of the usual or anypreferred form, the former being vertical and the latter horizontal, andboth have tongues T, relnovably engaging eyes I in the sides of theextensions X. By this means the guideboards when in place serve theirusual func- Fig. 2 is a tions and at the same time maintain thefeederframe in proper position; but when it is desired to fold the saidframe they may be removed by lifting their tongues out of the eyes, aswill be understood.

The feeder proper comprises top and bottom plates I, connecting theextensions X and necessarily divided at the meeting ends of theextensions, the bottom plate preferably having an extension-lip P,passing beneath the inner half of this plate, as seen. Upon the mainshaft M is a roller R, and journaled between the outer ends of theextensions X in another roller R, preferably covered by a curved plate Pas shown, and over these rollers pass endless belts or chains E,connected at intervals by cross bars or strips Q. The lower side of thefeeder-apron thus formed travels upon the lower plate and within thefeeder-frame, while the upper side travels upon the upper plate, as bestseen in Fig. 2.

The operation of this device is as follows: The extensions X beingopened and their fiat meeting ends coming in contact so as to supportthe outer portion thereof, the tongues T of the guide-boards G areengaged in the eyes I, as seen in Fig. 1, so that the grain may bethrown upon the feeder and will be carried to the thrasher thereby.Power is applied to the wheel m, which drives the roller R and causesthe endless apron to move in the direction of the arrow, and thecylinder Y is also simultaneously revolved in the wellknown manner. Thegrain being carried inwardly by the feeder drops upon and passes betweenthe cylinder Y and the concave C, where it is thoroughly thrashed, aswill be understood. The rapid rotation of the triangular beater B abovethe mouth of the hood H tends to compress the bundles of grain and passthem into said mouth, and the swinging fender S permits such passage,but prevents the grain or pieces of straw which may be thrown off fromthe cylinder flying back onto the feeder. It will be obvious that theguideboards G G may be transposed and placed at the opposite sides,respectively, of the feederframe and the grain fed to the machine fromthat direction.

After the device has been used and it is desired to move it to anotherpoint, the guideboards G are removed, the extensions X doubled on theirhinges it, so as to fold the entire feeder-frame, (the endless apronfolding with it,) whereby the curved plate P will be brought close up tothe mouth of the hood H and the Whole device will be very materiallyreduced in size.

Various changes in details may be made Without departing from the spiritof my invention.

What is claimed asnew is- 1. The combination, with a thrashing-machine,of extensions leading outwardly from said machine, each consisting oftwo pieces connected by a hinge on their upper sides,

plates connecting said pieces near their lip-- per and below their loweredges, the inner end of the lower plate of the outer piece having a lipextending beneath the lower plate of the inner piece, rollers jou'rnaledbetween said extensions at the mouth of the hood and at their on Herends, a curved plate around the outer roller, an endless apron movingover said rollers and along the upper faces of said plates, and meansfor moving said apron, substantially as described.

2. The combination, with the frame-work
